John Tojeiro was born at Estoril in Portugal, the son of a Portuguese father and English mother. When his father died, his mother took her your children back to Britiain and Tojeiro later studied at university in Britain and flew for the RAF.
His career as a builder of special car chassis started in 1951 and he sold his chassis as a kit for customers to build themselves but also sold completed cars. His Tojeiro-Bristol with a body closely resembling the Ferrari 166 Mille Miglia was the basis for the subsequent AC Ace (q.v.) from which the famous Cobra was developed. Tojeiro was paid £5 for every Ace and Cobra that Ace built. Tojeiro used Jaguar, Bristol, MG and Ford Anglia engines.
